  1. Hi Dzo,

    I have Avic mrz05 and i have been unable to change the language to English, kindly assist.

  2. AVIC-MRZ99 Custom Firmware / Testmode

    One thing you can try is to delete or create an empty file called "PRG.FLG" in /USER, this will swap to the other application firmware installation but it won't help if the problem is with the base OS. Also, if you start up the unit in engineering testmode, there are some tests it can run but you'll need google translate on your phone to navigate the menus.
  3. AVIC-MRZ99 Custom Firmware / Testmode

    OK, Here's a first attempt at a translation for MRZ85. I can't test this so it may not work. Rename it to PF090JPJPN.LNG PF090JPJPN_85ENG.LNG

  5. AVIC-MRZ99 Custom Firmware / Testmode

    There will probably be other language files, e.g. PF090JPENG.LNG, just copy one of these over PF090JPJPN.LNG.
  6. AVIC-MRZ99 Custom Firmware / Testmode

    If you post your old PF090JPJPN.LNG file here, I'll see if it's similar to one of the other models or make a new translation. If you don't have the old file, use one of the others, e.g. PF090JPENG.LNG
  7. AVIC-MRZ99 Custom Firmware / Testmode

    Put this testmode key onto a usb stick or sd card: TESTMODE.KEY And switch on the unit. If this doesn't bring up testmode then there is nothing much you can do. If it gets you into testmode, then you will need to find somebody else with the same model as yours and copy their PRG0 folder. You should never have deleted the PRG folders
  8. Hello. I bought a car from Japan with Avic-mrz02. I tried to replace the files with your instructions, but nothing happened. Can you help? I enclose a copy of the original firmware. And tell me how much money it costs. Thank you in advance


  9. Hello Dzo,

    Sorry to knock you over this issue since I can see that you are quite busy. 

    I was just wondering whether you still have the backup for MRZ99 ? 

    I downloaded the zip file from your post no 59 on my Sd card and then changed the script to SD/ from USB. After inserting the SD card the installer started in a red background and then changed to green and it keeps on rebooting.

    As of now my player is stuck on the screen as I have posted below but I can hear audio when I insert a Cd into my MRZ99, but I can enter testmode. Please help me !

    Also the very same SD card that I used for the backup isn't working so I don't ave any backup

  12. Hello, I have seen your posts in the forum, I have a MRZ05 also and am having problems to set it up. Please can you help me ? 

    I copy the file from the SD but when I go to the folder to paste it does not allow paste. I tried so many times. 

    Also I made a mistake that i did not back up when I deleted the original PF090JPJPN.LNG

    I would so much appreciate any help ... I have done this to my Mothers car as way to surprise her but now she is mad at me becuase it is not working !

    Thank you so much
